++ I was thinking of driviving back up to Parakou/N'dali and go to Abuja from there. How is the road ?
HIGHLY recommended to do this. Fine Tarmac to Parakou and up to the turning for Nikki. Dirt piste with corrugations to the border, fine fine.
After the border you should turn off (left) the good sealed road after about 10-30km(??) (at a roundabout )and follow the dirt piste towards the dam/reservoir/New Bussa. Nice area, only one checkpoint in a village and avoids all the police hassle and trucks on the sealed road. If dry it is a little slow but fine fine. All in tracks4africa if you have it? Else email me.
++ Do they still alow camping at Sheraton in 2013 ?
I believe so, but for a couple of dollars a night now - I think because of some idiots who camped previously. Definitely worth going, its fun ;-) If they do say no at the gate, go and politely ask the manager - gate staff don't always know what is happening.
++ Do you know how easy is a Cameroon visa in Abuja ?
Madame Claire is a bit of a bossy bitch, but if your ultra polite and give her the illusion of having some power she will do in one morning for you - easy enough.
++ Is it worth trying to get any other southbound visas there or pick them up later ?
Congo embassy is just a few houses down from Cameroon - did it in 10 minutes so worth getting unless you plan on spending 6 months in Cameroon/Gabon etc. Seems they charge more the better dressed you are at the Congo embassy?!?.
Gabon was stupidly expensive in Abuja and took a week. Most get in in Yaounde, but they are arrogant pricks in the embassy there, you need to wear trousers, collared shirt, shoes etc.
Angola no longer possible I believe. Try though?!
DRC was possible in Abuja if you had your Angola visa in advance - try it anyway, they weren't that helpful and wanted money to lift a finger, you need to blab some bs to them - had it in one day in the end.
Abuja is a modern city with hardly any traffic by African standards, and if you can camp at the Sheraton its worth doing as much as you can here- Yaounde is not a very nice city in my experience and the old Swiss bastard who runs the mission has ruined it as an overlanders place to stay.
++ A lot of questions I know but would appreciate any up to date info you can pass on.
No problem, I'm sure you will 'dash me' when you can ;-p
Keep your wits about you at all times in Nigeria, people are super friendly but there is a lot bubbling under the surface and plenty of dodgy police, be polite, smile a lot, super friendly, but very firm. Do not follow the police anywhere, or go to the station or any other such thing. You might get offers to be kidnapped at the Sheraton like I did!
Have fun! Wish I was there again now!!
